1 John 3:1-2; 1 John 3:10; 1 John 5:2

1 John 3:1-2

1 Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.

2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.

1 John 3:10

10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.

1 John 5:2

2 By this we know that we love the children of God, when we love God, and keep his commandments.
